Answer 1

Step-by-step explanation:

72-75/420

= -3/420 ( divede kar ke dekh lo yahi hoga )

Answer 2

= 2 / 5 * 3 / 7 - 1 / 6 * 3 / 2 + 1 / 14

= 6 / 35 - 1 / 4 + 1 / 14

= 6 / 35 - ( 14+4 ) / 16

= 6 / 35 - 18 / 56

= ( 6*56 - 18*35 ) / 35*56

= ( 336 - 630 ) / 1960

= -294 / 1960

= -147 / 980. --------- ( divisible by 2 )

= - 3 / 20 ------------

( divisible by 49 )
